I have been looking into adding this product to my services for awhile now. It's not a pigmented coating like the Nutech roof coatings that has been discussed in the past. It is a nano technology idea but it is transparent. I know many on this forum are painting & building contractors, any thought's. It seems to be internationally recognized and used. If it does what it says it can do its worth checking out.
